GAS-LIGHTER ATTACHMENT.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed September 21, 1906. Serial No. 335,555.

To all whom it mag/concern.-

Be it known that I, WI LIAM RocHE, a citizen of the United States, residin at J ersey City, county of Hudson, and tate of New Jersey, have invented certain new and useful Improvements in Gas-Lighter Attach ments, fully' described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates generally to improvements in gas lighters of that class which are adapted for use in connection with dry cell batteries, and particularly to an i1nproved means for attaching the lighter to the battery cell, and the invention has for its object the production of a gas lighter which may readily be attached to dry cells of varying sizes which shall be simple, cheap and durable.

In the accompanying drawings, with reference'to which the invention will now be derepresents a side View of a dry battery .cel showing the gas lighter attached thereto, certain parts being broken away. Fig. 2 is a view looking in the direction of arrow 1, Fig. 1. Fig. 3 is a plan view, partly in section, of the construction shown in Figs. 1 and 2, certain parts being omitted. Fig. 4 is a side view of a cell showing a modified form of attaching the lighter, certain parts being broken away, and Fig. 5 is a plan view of the construction shown in Fig; 4.

Referring now to the drawings which illustrate the invention in its preferred form 1 indicates generally the gas lighter proper. The gas lighter shown is a lighter adapted for lighting gas stoves, etc.'where it is desirable to keep the hand out of close contact with the gas, though the invention is adapted for use with other gas lighters of the class referred to, and the construction shown is that usually In this construction there is provided a wire 2, whi ch wire is incased for a portion of its length in a hollow rod 3. This wire terminates at the lighting end in a contact piece 4 screwed or soldered on the end of the rod. Except for such contact with contact piece 4 wire 2 is of course insulated from red 3. The contact piece 4 is screw threaded at one end and is adapted to receive a plug 6, which plug has the usual piece of platinum wire which is made incan descent by the passage of the current and forms the lighter, the platinum wire being ters.

protected by a cap 7 provided with perforations for permitting access of the gas to the wire. This gas lighter 1 may be attached to the dry cell C in any suitable manner to allow of its attachment to cells of varying diame- Preferably and as shown, there is provided on the lower end of the rod a part 8 of conducting material such as brass, this part 8 beingsoldered to one side of the rod so as to permit the wire 2 to pass to one side of it as shown. While this part 8 is shown as a separate piece soldered on the rod, and is preferably employed as being stronger, it may if desired be formed integral with the rod. This part 8 1s formed as shown (see Fig. 2) with a flattened bottom portion 9, this flattened bottom portion being provided w th a slot 10 which slot 18 adapted to fit over the shank of the screw 11 which passes through the top of the carbon electrode 12, thus forming a contact, which is held in contact with the carbon electrode 12 by .the screw nut 13.

The means provided by the present invention for attaching theivire of the-lig terto the other electrode ofthe cell "are such that the lighting attachment can readily be attached to any of the standard dry cells, these dry cells varying somewhat in diameter. In the preferred form and as shown there is provided a band or ring 14 of a conducting material which is adapted to be placed around the cell. The ends of this band or ring are formed with projections or wings 15, through which passes a screw 16, the screw being provided with a nut 17 by tightening or loosening which the band may be increased or de creased in diameter, thus permitting it to be fitted to cells varying considerably in diameter. On this band 14, at any suitable portion of its periphery, is suitably secured, as by soldering, a finger 18 of resilient conducting vmaterial, which linger is normally held out of contact with the zinc electrode of the cell, but which is adapted to be pressed or sprung into contact with the zinc electrode 19. It of course obvious that to make the co-.tact when the lighting attachment is put on an ordinary paper or paste-board covered dry cell it is necessary to shave or cut away the paper or pasteboard, as shown at 5 in Fig. 2, to expose the zinc electrode. The lower end of wire 2 hassecured to it a metal contact piece 19 fitting over screw 16 and held incontactwith projection or projections If), so

that when finger 18 is pressed inwardly into contact with the zinc electrode the circuit from the battery completed through plug 6.

It will be seen that with the construct on described, a very simple and efficient lighting attachment is provided, it being necessary in order to use the same when one drycell has become exhausted simply. to unscrew the contact 13, releasing the part 8., unscrew the nut 17, permitting the ring or band 14 to spread and lift the whole attachment from the exhausted. cell and replace it on the new cell by fitting the band 14 around the cell and screwing it firmly into place and securing the part 8 in place on the negative electrode with the nut 13.

In Figs. 4 and 5 a modification of the construction is shown, by the use of which it becomes unnecessary to cut away the paper or paste-board from the cell on which the lighting attachment is to be placed. In this construction the lighter and its attachment to the negative electrode is the same as that hereinbefore described. Instead, however, of having the finger 18 contact with the zinc electrode below the top of the cell, the finger is arranged to contact with the ordinary contact piece 20, which is provided on all ordinary dry cells. In the construction shown, there is provided a ring or band 21, which is of conductin material, adapted to surround the dry cell, t e ends of this ring overlapping, as shown at 22, Fig. 5. Bearing against the inside end 23, of this ring, is a screw 24, which passes through the outer end of the ring 25, the two portions of the band 23, 25, being forced together or over each other by a lock nut 26 on the screw 24, the contact piece 19 on the end of the wire 2 .being placed between the two parts of the nut and firmly held in position. The ring or band 21 is slipped down over the cell until the finger is in a position to contact with the contact 20, the ring then being securely fastened around the cell by the nut and screw 2.6, 24.

What is claimed is 1. In a gas lighter attachment for use with dry cell batteries, the combination of a. lighting device, a circuit therefor and means for detachably connecting the terminals thereof with the electrodes of the battery comprising a s lit band or ring for one terminal adapte to encircle the battery cell and provided with manually operable circuit closing means, substantially as described.
